Patent GB-2032571-A (GB)
Title: Improvements in or relating to mounting devices for water-piping
IPC: F24D3/14
Filed: 1979-09-11
Abstract: A mounting device for water- piping 4 comprises curved elements 2 welded fast on to bars (1a, 1b) which extend transversely to the pipe sections, parallel to each other with mutual spacing and which may be secured to a floor. The sector angle of the curved elements is greater than 180 DEG ; they serve the purpose of laying jigs or templates for the connecting bends of the piping in a meander arrangement. The two extremities of each curved element each have co- ordinated with them and with mutual spacing, a guiding section 3 which is also welded fast on the bars (1b, 1c). The curved elements and the guiding sections have an arcuated cross- section of identical radius which corresponds to the pipe radius. The concave side of the curved element cross-section is outwardly directed, whereas the concave side of the cross-section of the guiding sections faces towards the co-ordinated terminal portion of the curved element. The curved elements and the guiding sections thus form reception troughs for the pipe which prevent the pipe laid in from emerging in upward direction. The curved elements in conjunction with their guiding sections render it possible to keep the spacing between the parallel pipe sections smaller than the diameter of the curved elements. <IMAGE>

Title: Automatically applied brakes
IPC: B60T1/06
Filed: 1980-05-22
Abstract: As a safety feature, the driver's seat of an industrial truck has a switch 2 which senses when the seat is empty and which then applies a brake to the traction motor 3. The switch 2 operates a solenoid 12 which in turn operates a hydraulic valve (not shown) to depressurise a piston and cylinder 11 which normally holds the brake off against a tension spring 10. If the driver gets off his seat, the spring 10 pulls the brake on. For normal operation with the driver on his seat, the solenoid moves the valve 12 to a position where the piston and cylinder can be pressurised. The power steering pump may be used to generate the pressure. A separate parking brake may be provided although the traction motor brake may be used as a parking brake. <IMAGE>
